Abstract
A laminated glass article having a core layer made from a glass that is not ion-exchangeable, and a clad layer made from a glass that is ion-exchangeable. The laminated glass article has a maximum compressive stress in the clad layer from about 0.05 GPa to about 0.7 GPa, and a compressive stress at an inner surface of the clad layer directly adjacent to the core layer from about 20% to about 45% of a compressive stress at an outer surface of the clad layer. A slope of a stress profile in the clad layer is substantially linear. Methods for manufactured such a laminated glass article also are disclosed.
